ORE-SEPARATOR.

SPECIFCATION forming part of Letters Patent N0. 414,706, dated November 12, 188,9.

Application iled May 24, 1889.

To all whom, t may concern:

Beit known that I, WILLLAM Hoeren, of Ticonderoga, county of Essex, State of New York, have invented an Improvement in Ore- Separators, of which the following description, in connection with the accompanying drawings, is a specification, like lett-ers on the drawings representing like parts.

This invention has ,for its object the production of a novel ore-separator adapted to be effectively used in separating coarse and fin ely-pulverized ores, my improved separator being capa-ble of being employed both for mining and laboratory purposes.

In accordance with my invention a preferably concave pan or table is mounted on a reciprocating bed to rotate thereon, and the bed 1s suspended, as will be described, so that one end of the said bed is raised on its movenient in one direction, whereby the heavier particles in the panviz., the ore-are thrown outwardly toward the circumference of the pan, and thus separated from lighter particles or earthy matter, which are preferably washed toward the center of the pan, where they are Vdischarged into a suitable chute.

My invention in ore-separators consists, essentially, in the combination, with a revolving pan or table provided with an opening, of a reciprocating bed having an opening to register with the opening in the said pan and upon which the said pan or table is revolved, substantially as will be described.

Other features of my invention will be pointed out in the claims at the end of this specification.

Figure l is atop or plan View of an oreseparator embodying my invention; Fig. 2, a longitudinal sect-ion of the apparatus shown in Fig. .l on line a: fr; and Fig. 3, a transverse section of the apparatus on line y y, Fig. 2.

The frame to support the working parts of the apparatus consists, as herein shown, of sides a c" and end pieces a2 a3, sustained by suitable uprights ai. The side pieces a d',

'near one end of the apparatus, have secured to them uprights or brackets 0,5 al", forming bearings for shafts CLT 0,8, upon which are mounted links a9 am, to which are secured one end of side bars n.12 cl3, united by crosspieces al", the said side bars 0,12 a and crosspieces al" forming the reciprocating bed of Serial No. 311,981. (No model.)

the apparatus. The rear end of the reci procating bed is sustained, as herein shown, by links ab", having their upper ends pivoted to the side bars cl2 ds and their lower ends pivoted, as at al, to a firm or solid portion a of the frame-work. The reciprocating bed supports a bed-plate o, hinged, as at b, to one side bar, as cl3, and having its other end vertically adjustable by means of bolts or rods h2, extended up through the side bar cl2 and provided with ad j Listing-nuts b3 h4. The bedplate b is provided-with a circular opening surrounded by a flange or collar Z115, upon which the preferably circular pan or table b5 is turned, the said pan or table being provided with a central opening and having secured to or formin g part of it below the said opening a hollow axis bl, provided with a langet, which rests directly upon the flange 1715. W'ithin the hollow axis bl is located a pipe h3 of smaller diameter, forming with the.

hollow axis b1 an annular space, which is preferably divided into pockets bw by plates b9, the said pipe being secured to the plates b9, which are soldered or otherwise fastened to the hollow axis. The pan or table if is preferably made con caved and provided with a circular rim h2", to which is secured, as by partition-plates or tie-bars hw, a preferably conical ring Z113, which forms with the rim of the pan a space divided into chambers Z225 by the plates 512, into which the pulverized ore is fed.

The reciprocating bed is operated, as herein shown, by cam-shaped arms c on a hub secured to a shaft c', having bearings in side bars c2, herein shown as bolted to the crossbar a3 of the frame. The cam-arms c, as herein shown, act on a buffer G20, secured to or forming part of a box or frame c3, joined by a connectingerod cl to the cross-bar au, and produce movement of the bed in one direction, as indicated by arrow 20, the said bed being moved in the opposite direction, as herein shown, by a spring c5, secured to a block or support c6, fastened on the connect ing-rod. The main shaft c is provided with a driving-pulley d, and, as shown, with a conepulley dx, connected by belt 02X to a conepulley di on a shaft d, provided at its end with a bevel-gear d' in mesh with a beveled gear d2 on a shaft h3, provided with a worm IOO Z4 in mesh with a gear d5 on a shaft d6, connected by a band or belt d8 to the pan b5, by which rotation is imparted to the said pan and its attached parts. The main shaft c is also provided, as shown, with a hand-wheel e, by which the bed may be reciprocated when the main shaft is disconnected from the driving-shaft. (Not shown.) By suspending the front end of the bed with short links pivoted above the bed that end of the bed is thrown up on the forward movement of the bed, thereby imparting to the material in the pan a shoveling action.

In operation onel end of the bed-plate l) will preferably be raised by adjusting the nuts b3 b4 on the threaded rods or bolts so as to ineline or tip the pan toward one side, and the material to be treated will be fed into the pan at its lowest side. The pan is revolved by the belt d8, and at the same time it is being revolved the bed is reciprocated, and as a result of these two motions the crude ore or :material deposited in the pan at its lowest side is gradually carried around, as in the direction indicated by arrow 20, Fig. l. As the pan is revolved, the material therein is subjected to a shoveling action on the forward movement of the bed, caused by the spring c5, and the heavier particles-namely, the

orc-are thrown up the inclined bottom ofv the pan toward its rim, while at the same time the lighter particles-namely, the earthy matterare washed by a suitable spray-pipe, as am, toward the center of the pan, the earthy material mixed with water passing into the pockets 1310 at the lowest side of the pan, and

thence through a passage-way cl2, formed, as herein shown, by pipes cl3 e, suspended in any suitable-manner below the pan. The ore which is thus separated from its earthy matter is subjected to a spray or stream of water issuing through a pipe @15, when that portion of the pan holding the separated ore has been. brought into its highest position, which is substantially opposite the point at which the material or crude ore is first deposited in the pan. Vhen the separate ore has been brought into its highest position, as described, it is washed down the inclined bottom of the pan into the pockets blo at that side of the machine and passes down into a chute or hopper @20, leading in an opposite direction to the ,hopper 621, in which the earthy matter is deposited. In practice the ore washed from the highest position of the pan is completely separated from earthy matter.

My improved machine is especially adapted for treating finely-pulverized ores or slimes, and when it is to be thus used the buffers f, which are secured to the frame and located so as to be struck by the bed on its forward movement, are adjusted or brought nearer the bed, so as to' receive a great blow, and thereby cause an increased jar of the table or pan, and as a result cause the finer parti- 'cles of the ore to settle and adhere to the j with a revolving pan or table provided with a central opening, of a reciprocating bed having an opening to register with the opening in the said pan and upon which the said pan or table is revolved, substantially as and for the purpose specified.

2. In an ore-separator, the combination, with a concaved revolving pan or table provided with a central opening, of a reciprocating bed provided with an opening to register with the opening in the said pan, substantially as described.

3. In an ore-separator, the combination, with a revolving pan provided with a hollow axis, of a reciprocating bed provided with an adjustable bed-plate, whereby the said pan may be tipped or inclined, substantially as described.

4. In an ore-separator, the combination, with a concaved revolving pan provided with a hollow axis, of areciprocating ,bed provided with an adjustable bed-plate having an opening into which the hollow axis is inserted, substantially as described.

5. In an ore-separator, the combination,

with a concaved revolving pan provided withA a hollow axis, of a bed provided with an adjustable bed-plate having an opening into which the hollow axis is inserted, links, substantially as described, to support said bed IOO IIO

at its opposite ends, and means to reciprocate said bed, substantially as described.

6. In an ore-separator, the combination, with a concaved revolving pan provided with a hollowaxis,of a reciprocating bed provided with an adjustable bed-plate having an opening into which the hollow axis is inserted, a pipe bs, located in said hollow axis, and plates b9, to form pockets bw between said hollow axis and pipe 68, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
